Hi All, We have submitted a new draft related to Alto caching and subscription. We felt that the existing HTTP based caching mechanisms are not suitable for caching Alto map information.
We also proposed a new mechanism for subscription and notification which we think will help reduce redundant traffic between alto nodes. Your comments are highly welcome. http://www.ietf.org/id/draft-alto-caching-subscription-00.txt Regards, Sreekanth Madhavan, on behalf of all authors -----Original Message----- From: [email protected] [mailto:[email protected]] Sent: Wednesday, February 22, 2012 10:29 AM To: [email protected] Cc: [email protected]; [email protected] Subject: New Version Notification for draft-alto-caching-subscription-00.txt A new version of I-D, draft-alto-caching-subscription-00.txt has been successfully submitted by Sreekanth Madhavan and posted to the IETF repository. Filename: draft-alto-caching-subscription Revision: 00 Title: ALTO Caching and Subscription Creation date: 2012-02-22 WG ID: Individual Submission Number of pages: 19 Abstract: The specification of the ALTO protocol uses map based approaches assuming that the information provided is static for a longer period of time. But in some cases network operators reallocate IP subnets from time to time which in turn changes the mapping partitions[I- D.ietf-alto-deployments]. Since the ALTO clients are unaware of the map information changes, clients need to query the servers for every service request and many such requests are redundant because the information was not changed. The purpose of this memo is to provide two mechanisms which will help the ALTO clients to be informed of the map information changes. a) ALTO clients cache the map information and the servers provide the expiration time for invalidation. b) ALTO clients can subscribe for event notifications from the server The IETF Secretariat _______________________________________________ alto mailing list [email protected] https://www.ietf.org/mailman/listinfo/alto
